D-STAR OPERATION (BASIC)
About the DR function
You can easily use D-STAR repeaters with the
D-STAR Repeater (DR) function� With this function,
you can select the preset repeater or frequency in
"FROM" (access repeater), and a target call sign in
"TO" (destination) on the DR screen, as shown right�
NOTE: If the repeater set in "FROM" (Access
Repeater) has no Gateway, you cannot make a
Gateway call�
To display the DR screen, hold down

Ways to Communicate with the DR function
With the DR function, the transceiver has 3 ways to
communicate�
Local Area call: To call through your local area
(access) repeater�
L You can use an FM repeater�
Gateway call:
To call through your local area
(access) repeater, repeater gateway,
and the Internet to your destination
repeater or individual station's last
used repeater, using Call Sign
Routing�
Simplex call:
To call another station not using a
repeater�
NOTE:
• Using the repeater list is required to use the DR
function� (p� 10-15)
• Before operating in the Duplex mode, BE SURE
to check whether the repeater is busy or not� If the
repeater is busy, wait until it is clear, or ask for a ‛break'
using a method acceptable to your local procedures�
• The transceiver has the Time-Out Timer function for the
DV Repeater operation� The timer limits a continuous
transmission� Warning beeps will sound approximately
30 seconds before time-out and then again immediately
before the time-out�
To begin Digital mode communication using other than the DR function
To begin Digital mode communication using other
than the DR function, you can use the VFO mode,
Memory mode, or Call Channel mode� This manual
description focuses on the DR function operation,
which can be easily set up� If you want to use
other than the DR function, see the procedures
as described to the right, or select a repeater in a
Memory channel�
